DETAILED DESCRIPTION

[0014] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0015] like Figure 1 As shown, this embodiment discloses a retractable electromagnetic lock, including a lock body 1 2, a lock body 2 3, and a lock body storage cavity 13, wherein the lock body 1 is provided with a runway circular lock core 1 with a slot, a slider 4 is provided on the outer wall of the lock body inner cavity, a slide rail is provided inside the lock body storage cavity, and the lock body 2 3 can slide along the inner wall of the lock body storage cavity.

[0016] The lock body 2 includes a lock body cavity with an opening close to the lock body 1 and a limiting plate 11 away from the lock body 1. The end of the lock body cavity close to the lock body 1 is conical. The lock body cavity is provided with an electromagnetic conversion part 10, a first spring 9, a slider 8, and a limiting ball 7. The limiting ball 7 is located on one side of the conical end of the lock body cavity. The limiting ball 7 cooperates with the slot of the lock core 1 to achieve lock body locking. The electromagnetic conversion part 10 is located on the side of the lock body cavity away from the conical end. The first spring 9 is connected to the slider 8, and the slider 8 rests on the limiting ball 7. The slider and the limiting ball are both made of metal materials. When the door lock is started, the lock core of the lock body 1 is inserted into the lock body cavity of the lock body 2, and the lock core passes through the gap between the limiting balls.

[0017] The electromagnetic conversion part is composed of an iron core and a coil. When the code is scanned and the power is turned on, the iron core will become a magnet, attracting the slider and the limit ball compression spring to move closer to the electromagnetic conversion part.

[0018] The lock body receiving cavity is provided with a second spring 15 and a motion buckle 14 at one end away from the lock body, and the motion buckle 14 is adapted to the limiting groove on the limiting plate 11 .

[0019] In this embodiment, the limiting slot is provided with a positioning point 1 5 on the side close to the inner cavity of the lock body, and a positioning point 2 6 on the side away from the inner cavity of the lock body, and the positioning point 1 5 and the positioning point 2 6 are connected by a transition slot 12. The positioning point 1 5 and the positioning point 2 6 are located on the center line of the limiting plate, and the transition slot is symmetrical with respect to the center line of the limiting plate.

[0020] The transition slot smoothly connects the first positioning point 5 and the second positioning point 6. The transition slot may be in a fold line shape, an arc shape or other shapes. In the present embodiment, the transition slot 12 is in a fold line shape.

[0021] In the normal state, the motion buckle is located in the second positioning point, and the second spring is against one side of the limit plate; in the storage state, the motion buckle is located in the first positioning point, and the second spring is compressed.

[0022] One end of the motion buckle is rotatably connected to the top of the lock body storage cavity, and the other end is located in the limiting slot and can slide along the limiting slot.

[0023] This embodiment also discloses a smart vending cabinet, which is equipped with the above-mentioned retractable electromagnetic lock, wherein the lock body 1 is pre-buried in the door body of the smart vending cabinet, and the lock body 2 and the lock body storage cavity are pre-buried in the box body.

[0024] In the use scenario of the smart vending cabinet, when in the locked state, the electromagnetic lock state is as follows Figure 2As shown, the lock core slot in lock body one and the limiting ball in lock body two constrain each other, and lock body one is locked; the customer scans the code and completes the power-on. The electromagnetic conversion part in lock body two generates magnetism after power-on, attracting the slider in lock body two to move to the electromagnetic conversion part, generating pressure on the first spring in lock body two. The first spring is compressed, and the internal limiting ball moves toward the lock body cavity of lock body two, releasing the lock core of lock body one, completing the unlocking action, and lock body one can be safely pulled out. The unlocked state is as shown in FIG. Figure 3 shown.

[0025] After completing the unlocking action, the customer selects the required product and then closes the door. The electromagnetic conversion part is powered off and loses its magnetism. The slider in the lock body 2 moves away from the electromagnetic conversion part under the action of the first spring. The first spring returns to its original position and pushes the limit ball to move toward the closing part of the conical inner cavity. At this time, the door closing action is that the lock core of the lock body 1 is inserted into the gap of the lock body 2, and the slot of the lock core and the limit ball continue to restrict each other to complete the locking action.

[0026] When smart vending is not needed, the door of the vending cabinet does not need to be locked, and the electromagnetic lock can be stored. Figure 4 As shown, the lock body 2 is placed as a whole in the lock body storage cavity. By pressing the lock body 2, an extrusion force is generated on the second spring, and the motion buckle moves from the positioning point 2 along the transition slot to the positioning point 1. The motion buckle cooperates with the positioning point 1 on the limit plate to limit the lock body 2 and complete the storage. At this time, the lock core of the lock body 1 is separated from the inside of the lock body 2, and the locking action fails. The normal door opening and closing action can be performed. When the smart locking function needs to be used again, the lock body 2 is pressed inward again. At this time, the motion buckle moves out from the positioning point 1, along the transition slot, and under the push of the second spring, the motion buckle enters the positioning point 2, and the lock body 2 pops out, and the smart locking can be achieved.

[0027] The above embodiments are only exemplary embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the essence and protection scope of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present invention.
